# qtimetamux Source: [https://docs.qualcomm.com/doc/80-70022-50SC/topic/qtimetamux.html](https://docs.qualcomm.com/doc/80-70022-50SC/topic/qtimetamux.html) Qtimetamux 插件使用帧匹配技术将基于 ML 字符串的后处理结果（后处理插件输出）或 CV 信息关联或附加到原始帧（如[GstMeta](https://gstreamer.freedesktop.org/documentation/gstreamer/gstmeta.html#GstMeta)）。 该输出会与 qtioverlay 等插件共享以进行渲染，或者向下传递到 ML 推理 pipeline 以进行进一步的推理。 也可以附加 [appsink](https://gstreamer.freedesktop.org/documentation/app/appsink.html?gi-language=c#appsink-page) 插件并在用户定义的应用程序中接收 [GstBuffer](https://gstreamer.freedesktop.org/documentation/gstreamer/gstbuffer.html#GstBuffer) 和 [GstMeta](https://gstreamer.freedesktop.org/documentation/gstreamer/gstmeta.html#GstMeta)。 Figure : 使用 qtimetamux 的 GStreamer pipeline gstreamer_pipeline_qtimetamux_c Sheet.3 Sheet.4 Sheet.17 GstBuffer GstBuffer Sheet.19 + GstMemory: 后处理 Gstreamer 文本中的信息格式 + GstMemory:后处理Gstreamer文本中的信息格式 Sheet.20 Sheet.26 Sheet.27 Sheet.28 ML 推理插件 ML 推理插件 Sheet.30 ML 预处理插件 ML 预处理插件 Sheet.33 Sheet.34 Sheet.36 Sheet.37 Sheet.44 Sheet.45 Sheet.47 Sheet.48 Sheet.49 qtimetamux qtimetamux Sheet.60 Sheet.61 Sheet.62 Sheet.63 Sheet.64 Sheet.65 Sheet.111 GST BIN GST BIN Sheet.51 GstBuffer GstBuffer Sheet.53 + GstMemory: 包含单个张量 + GstMemory: 包含下一个张量 + ... + GstMemory:包含单个张量+ GstMemory:包含下一个张量+ ...
